The sections may be disposed longitudinally of the wall tubing or may surround the tubing as desired. Each section consists of a strip having an interme' diate channel portion formed therein, the wall of said channel portion being provided with openings. One side wall of the channel portion extended into a scroll and the other side wall of the channel portion extends into a double fold and then terminates in a scroll. The scroll at the edge of one section adapted to interlock with the scroll at the edge of the adjacent section in the formation of the screen.

in the accompanying drawings Figure 1 is a horizontal sectional View of a tubing with the screen applied.

Figure :2 is a side elevational view showing a. tube with the screen applied thereto and extending longitudinally thereof.

liigure 3 is a perspective view of one of the sections of the screen.

Figure 4 is a side elevational view of a tubing showing the screen sections surrounding the same.

The screen consists of a number of sheet metal sections 1 each section having an intermediate channel portion 2 formed therein and the all of said channel portion being provided with openings 3.
